Abstract

A method for pretreating a sintering material using as a material at least two types of iron ore containing coarse grains and fine powder, using a first granulator to make the fine powder stick to coarse grains forming core grains so as to produce S-type granules, and using a second granulator to granulate only fine powder or mainly fine powder to produce P-type granules, which method producing the S-type granules by adjusting an amount of fine powder supplied into said first granulator so that the average stuck thickness of fine powder to the core grains becomes 50 to 300 µm and supplying the remaining fine powder not supplied to said first granulator to the second granulator.
